Displaying Snapshot copy disk consumption statistics

You can use the snap list command to view the disk space utilization by Snapshot copies. This information helps you determine an appropriate Snapshot copy reserve. The snap list command also shows whether a Snapshot copy is required for a replication operation, such as SnapMirror.

Step

  1. To display the Snapshot copy statistics for a volume, enter the following command:snap list vol_name
    vol_name is the name of the volume for which you want statistics.

    If you do not specify a volume name in the command, the output contains statistics about each volume in the system.

    Example
    The following example gives a sample output of the snap list command:
    systemA> snap list vol0
    
    Volume vol0
    %/used     %/total    date         name
